* Add retrieve_orders option.
* Run acme_certificate tests also for acme_account_info; use acme_account_info to get list of orders.
* Doing some quoting.
* Improve returned description.
* Improve link handling.
* Also fetch alternate certificate chains.
* Add retrieve_all_alternates option.
* Simplify code.
* Forgot when condition.
* Add tests for retrieve_all_alternates.
* Fixes.
* Moved utility function for link parsing to module_utils.
* Fix grammar.
* Bump container version.
* Use new URLs.
* Add IP certificate tests.
* Disable IPv6 IP from IP certificate.
Background: in CI, the ACME test container apparently has no IPv6 support.
Without IPv6 support, Pebble can't connect to validate, and thus validation
fails.
* Collecting PEM -> DER conversions.
* Using cryptography instead of OpenSSL binary in some situations.
* Moving key-to-disk writing for key content to parse_account_key.
* Rename parse_account_key -> parse_key.
* Move OpenSSL specific code for key parsing and request signing into global functions.
* Also using cryptography for key parsing and request signing.
* Remove assert statements.
* Fixing handling of key contents for cryptography code path.
* Allow to disable the use of cryptography.
* Updating documentation.
* 1.5 seems to work as well (earlier versions don't have EC sign function). Making Python 2.x adjustments.
* Changing option to select_crypto_backend.
* Python 2.6 compatibility.
* Trying to test both backends separately for acme_account.
* Also testing both backends separately for acme_certificate and acme_certificate_revoke.
* Adding changelog entry which informs about select_crypto_backend option in case autodetect fails.
* Fixing YAML.
* Added support for TLS-ALPN-01 verification.
* Unrelated commit to re-trigger tests.
* Added test for TLS-ALPN-01.
* Try to remove to_bytes in the hope that binary data survives in Python 2.
* Using Base64 encoding for TLS-ALPN-01 value.
* Using ACME test container for acme_account integration test.
* Removing dependency on setup_openssl. Waiting for controller and Pebble.
* More tinkering.
* Reducing number of tries.
* One more try.
* Another try.
* Added acme_certificate tests.
* Removed double key.
* Added tests for acme_certificate_revoke.
* Making task names more meaningful (during certificate generation).
* Using newer test container which integrates letsencrypt/pebble#137. Adding test for revoking certificate by its private key.
* Using new version of Pebble which limits the random auth delay.
* Simplifying certificates for revocation tests.
* Reworking acme_certificate tests (there are now more, but they are faster).
* Test whether account_key_content works.
* Preparing TLS-ALPN-01 support.
* Using official Ansible image of testing container on quay.io.
* Bumping version.
* Bumping version of test container to 1.1.0.
* Adjusting to new CI group names.
* Pass ACME simulator IP as playbook variable.
* Let test plugin wait for controller and CA endpoints to become active.
* Refactor common setup parts of tests to setup_acme.
* _ -> dummy
* Moving common obtain-cert.yml to setup_acme.
